ART OF DECORATING GLASSWARE.

SPECIFICATION forming part of Letters Patent No. 394,612, dated December 18, 1888.

Application filed February 20, 1888. Serial No. 264,641. (No model.)

To all 1071/0712 it 'nmy concern.-

Be it known that I, DANIEL RIPLEY, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in the Art of Decorating Glassware; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a side view of a glass tumbler, on which a pattern is partially formed, this figure being designed to illustrate one stage of my improved process of ormunentation. Fig. 2 is a similar view showing the completed pattern.

I11 forming frosted figuressuch as vines, leaves, &c.on glassware, it has been the general custom to employ a revolving wheel, against which the glass is held, and which makes the necessary frosted marks or lines on it. \Yhen the pattern is formed of lines of different thicknesses, the operation is necessarily very slow, because beside the care and skill required to form the whole pattern properly a considerable time is occupied in changing the wheels, several sizes of which must usually be employed before the pattern is completed, a broadrim wheel being needed to make the extended surfaces, wheels with narrower rims being necessary for the finerlin es, and very small wheels being needed for the small dots of the pattern.

My invention is designed to simplify the process of decoration, to save ti me and skilled labor, and to provide means whereby better effects can be produced than with the old style of wheel decoration.

To this end my invention consists informing a pattern 011 the glass in rough by means of a sand or emery blast, and then finishing it by the application of the necessary shadelines and other line lines by an engravingwheel. This is a rotatory wheel, on the edge of which is applied a mixture of emery and oil, which in the revolution of the wheel cuts the glass article which is held in contact therewith, producing the desired fine lines of the pattern. The engravingwheel, being fine and not subject to be blunted by wear, gives very delicate and beautiful effects, and enables the irregular or curved lines of leafpatterns to be produced with great facility.

The glass article is held beneath the revolving engraving-wheel in contact with the lower edge thereof, and the wheel being quite thin the pattern can easily be seen and followed by the workman, who is thus enabled to form it with greataccuracy.

In carrying my invention into practice I cut out a stencil which represents in rough the broad surfaces, spots, and thick lines of the pattern, place this on the glass, and then by means of a sand or emery blast I reproduce this pattern on the glass in the usual mode, as shown in Fig. 1. This forms the main part or body of the pattern very well, the effect being better than with a wheel, because it is perfectly regular and unmarked by the streaks or striations which so often appear when the wheel is used.

In order to complete the pattern, I take the glass article which is thus marked, and by holding it against a revolving engravingwheel I form on the plain frosted surfaces produced by the sand-blast the proper shadelines and rib-lines, and in the same way I form the stems and other connecting lines of the pattern. This produces the completed pattern shown in Fig. 2, which is ornate and finished, giving much better and different results than where the whole pattern is produced by means of a wheel.

The advantages of my improvement will be appreciated by those skilled in the art. It results in a great saving of time, and enables the glassware to be decorated much more rapidly and with a great saving of cost.

I do not claim, broadly, the production of a pattern by means of a sand-blast, nor the production of a pattern by means of a wheel; but

What I do claim is- An improvement in the art of decorating glassware, which consists in blocking out the groi'indwork of a pattern by a sz'tnd-blast, and finishing the said pattern by an engravingwheel, substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand this 15th day of February,A. I). 1888,

DANIEL C. RIPLEY.
